Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2604UARP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (Breakover: 300V/600V; Off-State: 220V/440V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 150 A; Peak Pulse 10/1000µs: 45 A; Hold Current: 150 mA)
• Element count (4 elements)
• Capacitance range (20pF, 35pF)
• Physical package (6-SMD, Gull Wing; Modified MS-013)
• Series designation (SIDACtor®)

The P2604UALRP meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2604UALRP is the direct substitute for the obsolete P2604UARP. Both components are electrically and mechanically identical across all specified parameters. The P2604UALRP carries Active product status, ensuring continued availability and supply chain reliability.

A significant advantage of the P2604UALRP is its ROHS3 compliance, compared to the non-compliant status of the P2604UARP. This compliance improvement is relevant for applications subject to RoHS regulations. The P2604UALRP is supplied in Tape & Reel packaging, which is standard for high-volume manufacturing environments.

Selection between these parts should be based on product availability, supply chain requirements, and regulatory compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the P2604UALRP be used as a direct replacement for the P2604UARP?

A: Yes. The P2604UALRP is electrically and mechanically equivalent to the P2604UARP across all specified parameters, including voltage ratings, current specifications, element count, capacitance, and physical package configuration.

Q: What is the primary difference between these two parts?

A: The P2604UARP is obsolete, while the P2604UALRP is active. Additionally, the P2604UALRP is ROHS3 compliant, whereas the P2604UARP is non-compliant. The P2604UALRP is supplied in Tape & Reel packaging.

Q: Are there any compatibility concerns when substituting the P2604UALRP for the P2604UARP?

A: No compatibility concerns exist. Both parts share identical electrical characteristics and the same 6-SMD Gull Wing package configuration, ensuring PCB layout and assembly process compatibility.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical electrical specifications.

Q: What packaging formats are available for these parts?

A: The P2604UARP was supplied in standard packaging. The P2604UALRP is supplied in Tape & Reel format, which is optimized for automated assembly processes.
